This could be a perfect pivot neutral b.
No, its similar, but the perfect pivot Eruption doesn't look like that.
Ike slides about 3-4 character lengths when doing Eruption during a run, the PP version of Eruption goes maybe one character length, and the weird reverse one goes the same as the normal running one, just backwards.
Now, this is just a theory, but I think both the button timing and WHEN IN THE DASH you do it are important.
See, I'm the one that figured out how to perfectly do Ike and Palutena's Sliding Counter and made a thread about it (
pre-patch, its gone now). How it worked was by inputting Counter at either the end of your initial dash or at the halfwaypoint , and it could be done at either of these points during a run.
For Ike you could input Counter just before his feet crossed or when his legs became fully extended during a run and he would slide about twice his normal legth.
Anywho; I'm kind've getting a similarly weird vibe with this, but its a fair bit harder due to also trying to time a reverse special during it rather than just a button press.
I'll try a few more minutes of testing (
I've made it happen five times in as many minutes, but still haven't figured it out yet), but I need to sleep too.
Edit: Just pulled it off three times in a row, STILL not 100% on the timing, but I think it has to be done faster than a regular reverse. It feels like it has to be reversed on the very first frame possible, I'm still having trouble in 1/2 speed (
I'd try 1/4, but that's TOO slow).
